MONITORING: IN-LINE CORROSION DETECTOR (ILD-X)
U.S PAT. No. 9,095736 and 9,839,802
General Description
The ECS In-Line Corrosion Detector is designed to provide an early warning indication of internal corrosion
activity in water-based fire sprinkler systems. The device is designed to be installed where corrosion is
most likely to occur: the air/water interface. A cross-section of the device shows the two key attributes
that allow for early detection of corrosion: an externally milled section of the pipe that creates a thin-wall
section and a pressure chamber created by an external sleeve welded over the pipe. The thin-wall section
of the device will fail before other system piping to provide an early warning indication. The In-Line
Corrosion Detector is equipped with a pressure switch to monitor the pressure chamber. The In-Line
Corrosion Detector can be remotely monitored through a buildings monitoring system, or locally through
the Detector Remote Test Station.
Installation Instructions
The In-Line Corrosion Detector is manufactured as a spool of piping with roll grooved ends for easy
insertion into the fire sprinkler piping using standard mechanical couplings (supplied by others). All
models of the In-Line Corrosion Detectors are eighteen (18) inches in length. The variety of pipe schedules
and metal are listed in the table under ordering information.
